Abstract
A silencer, for example an intake silencer for an internal combustion engine, may include a pipe for conducting a gas mixture. The pipe may be perforated at least in some regions. An absorption layer may at least partially surround the pipe for absorbing a sound transmitted by the gas mixture. An outer casing may encase the pipe. The outer casing may be perforated at least in some regions and may surround the absorption layer.
